The efficiency of the newly launched predatory mite Amblydromalus limonicus : biological control of thrips in cucumber

In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been examined for its potential to use as a biological control agent in cucumber production. A. limonicus can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci. Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the southern part of Sweden. The basic control agent used against thrips was the predatory mite Amblyseius swirskii. In selected areas, additional A.

Olika typer av täckning och samodling och dess påverkan på antalet skadegörare i en Pak choi odling :

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

Läraren och betydelsen av dennes kropp i idrott och hälsa : En kvalitativ studie om elevers förväntningar på lärare i idrott och hälsa gällande deras kroppsform och förmåga att genomföra fysiska moment i undervisningen

In this study, emphasis was situated around pupils? expectations regarding body shape and physical proficiency among teachers within the subject of physical education. Additionally, possible outcomes of failure to uphold such demands were put in relation to aspects of legitimacy. To enable such study a qualitative study including semi-structured interviews was conducted and carried through, involving six pupils in the third grade of upper secondary education. The pupils were mainly selected through a convenience sample with.

Njurfunktion hos hypertyreoida katter : en jämförelse mellan serumkreatinin och serumcystatin C

Hyperthyroidism and chronic kidney failure (CKD) are common diseases in older cats. It can be difficult to evaluate kidney function in cats suffering from both conditions simultaneously. In the daily clinic serum creatinine is the analysis of choice when evaluating kidney function and secondary glomerular filtration rate (GFR). This marker does not, however, detect kidney damage until about 75 % of the function is lost. There are several other techniques available when investigating GFR but none are readily available for the small clinic.

Fallstudie av kostnader i tornsilo och plansilosystem på en mjölkgård :

I have through a case study looked on a milkingfarm in Dalarna and been counting on what it would cost to increase the silagestorage. Today they have to little capacity on the existing towersilo because they built a bigger farm with more cows. The reason is that two families decided to start having the production on one farm together and moved all animals from one of the farms to the other farm. So for that reason I have looked on the costs to build a new towersilo or levelsilo. The goal has been not only to look at the buildingcost but also which operatingcost that is included with the different alternatives. I have taken tenders from two different towersilocompany, Bjurenwall and Svenska Neuero and taken tenders from Abetong for a levelsilo with roof and one without roof. The overall feed requirements on the farm is on 240 tonnes dry extract and the old towersilo hold 110 tonnes dry extract so the need for a new foundation is on 130 tonnes dry extract. I have through cost estimate been counting on the specific buildingcost for each buildingaltenative.

Mätning av Mikroläckage i Dentala Implantat

Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss. The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.

Ekonomin under omläggningsåren vid övergång till kravgodkänd produktion :

The purpose of these theses is to show the financial economical situation during the change from conventional dairy production to ecological production. The thesis is accomplished by collecting information from literature and interviews where needed. The target group of these theses is dairy producers who will transform their production from conventional dairy production to certified ecological dairy production. The theses emphasise on the economic situation during the adjustment years. For this I have studied a presently producing dairy farm.

An image-based method for identification of new inhibitors of Signal Transducer Activator of Transcription 1

Background: Chemotherapy and radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway. STAT1 was the first described transcription factor in the STAT family. STAT1 is activated by stimulation of signaling proteins such as type II interferon (IFN- ?) and the activated STAT1 translocates from cytoplasm to nucleus.

Upplevelser av ätstörningsbehandling: en uppföljning av de långsiktiga effekterna av en dagvårdsbehandling.

The aim of this essay is to examine which help a group of women with eating disorders had from thier treatment in daycare in 2004. The aim is to examine how the women have experienced this treatment and how they live today. The central questions are: what was their life situation like before the treatment, what was their experience of the treatment, how could the treatment have been better and how are their lives today? The method is based on qualitative interviews with seven women who were all in the same treatment for eight weeks at Capio AnorexiCenter in Malmö. The women have also redone tests that were done right before and right after the treatment.

Styrkan i OEE som arbetsmetod

The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered.

Höghöjdsanpassning av BvS10 : Konceptstudie för optimering av överladdningssystem

This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.

Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt

When harvesting ley you hope to get a fast drying and a faster harvest. If there is a system with round bales, you need to have a dry matter close to 45 %. To make this as fast as possible, there is made a machine which pick up the grass with an pick-up. It turn the grass over and put it behind the machine (figure 2 and 4). There are few tests to prove the efficiency of this machine.

Kommunikation och Prestation : Aspekter på förhållandet mellan teamkommunikations innehåll, frekvens och problem, och teamresultat, studerat i en militär flygsimulator för grupper

A study of communication content, frequency and problems was performed at the Swedish Air Force Air Combat Simulation Centre, FLSC. The purpose was to investigate the connection between team communication and performance variables, to study communication problems during air combat and to employ and develop the PILOT method of communication problem analysis. Ten fighter pilots and four fighter controllers engaged in simulated air combat beyond visual range in teams on two sides, Blue and Red, with four pilots and one fighter controller each. Eight such training runs lasting 15 to 25 minutes were analyzed with regard to the Blue team?s communication during launch situations, i.e.
